I just came across the following paper describing how Toyota analyzes each and every job for physical hard and dangerous work condition. I wish more plants would use such a work condition measurement tool.
Now, I’m in the Service Industry. How could that be done similarly? Burden would have to be seen from the point of view of a worker’s mind perspective.
Just taking into consideration the formula
Weight burden index (B)=sum(WxNxL)xT/1000 could yield something like:
- Weight = difficulty of work: from simple mental calculus to highly mental computation & decision making…
- Number = number of times per job the “heavy” work has to be done
- L = Movement coefficient = an index of where that work occurs, of the conditions: under time constraints (eg. harder at the end of the process with a deadline than at the beginning)? Is it well defined (existing standard)? Is it always changing? Does it requires deep thinking before working? Risks of errors? Does it fit into a bigger picture (part of a bigger process)?
- Time coefficient = duration of difficult task
Of course, evaluation the TVAL of a work has no point if it’s not for its improvement…
